Multiflex V4 Twin Lever Top Mount Control

The Multiflex V4 / LM-V-4 Twin Engine Top Mount Control Lever is a fully mechanical marine remote control with two dual-action levers. Each lever operates both the throttle and gear-shift functions for one engine, allowing a conventional twin-engine installation to be controlled from one top-mounted unit. The V4 includes forward, neutral and reverse detents, neutral warm-up functionality and a chrome housing intended for marine applications.

What Is the Multiflex V4 Used For?

The V4 provides mechanical throttle and gear control for two engines from one helm position.

It can form part of a correctly specified:

• Twin-inboard engine installation
• Twin-sterndrive installation
• Twin-outboard installation where the control cables and engine-end adapters match
• Main helm control system
• Flybridge or exposed top-mount control position
• New mechanical engine-control installation
• Replacement of an existing V4 control
• Retrofit after complete dimensional and cable-interface checks
• Installation using compatible universal 3300 / 33C-style cables
• Installation using compatible engine-specific Multiflex cables

Multiflex does not publish a definitive engine-make, engine-model or horsepower list for the V4. Compatibility depends on the control cables, engine-end connections, cable travel, operating direction and available installation space.

How Do the V4 Dual-Action Levers Work?

The V4 has two levers, with one lever assigned to each engine. Each lever combines gear selection and throttle operation.

• One dual-action lever controls the first engine
• One dual-action lever controls the second engine
• Each lever provides forward, neutral and reverse selection
• Each lever also controls engine speed
• The engines can be operated together or independently

The exact movement sequence, lever travel and cable attachment positions must be confirmed from the current V4 installation instructions and engine-control requirements.

What Is Included?

• 1 x Multiflex V4 / LM-V-4 twin-engine top-mount control assembly

The control is shown with two operating levers, two red lever knobs, a chrome upper housing and two below-panel mechanisms. No complete manufacturer packaging schedule was located.

Not included unless expressly stated:

• Throttle cables
• Gear-shift cables
• Engine-specific cable adapters
• Engine-side ball joints or clevises
• Cable support clamps
• Secondary control station
• Dual-station selector units
• Engine wiring harness
• Ignition switch
• Power-trim switches or trim wiring
• Engine synchronisation system
• Steering components

How Many Control Cables Does the V4 Require?

A conventional twin-engine V4 installation normally requires:

• 2 x throttle cables
• 2 x gear-shift cables
• 4 x control cables in total

The cables are selected separately according to their routing length, engine connection and cable family.

Which Multiflex Control Cables Are Compatible?

Current Australian product page:

• EC-133
• EEC-133
• EC-133R
• EC-016

Broader global product listing:

• EC-033
• EC-133
• EEC-133
• EC-133R
• EC-043*
• EC-016

Before ordering, confirm cable length, travel, end fittings, operating direction, bend radius, connection kit and engine compatibility.

Is the Multiflex EC-043 Cable Compatible?

The global cable list includes EC-043 with an asterisk, but the reviewed product data do not explain the asterisk or identify the exact adapter required.

Confirm the control-side adapter, cable clamp, terminal arrangement, travel and engine-end connection before using an EC-043 heavy-duty cable.

Is a Neutral Safety Switch Included?

Multiflex sources use both the descriptions Neutral Safety Switch and Neutral Safety Switch Indicator. The exact switch type, wiring, terminal arrangement and electrical rating are not published in the product data reviewed.

Confirm the supplied component and test that each engine can start only when its shift mechanism is in neutral.

How Does Neutral Warm-Up Work?

Multiflex lists neutral warm-up as a V4 feature. The reviewed product information does not describe whether the current control uses a pull-out lever, push button or another mechanical shift-disengagement method.

Follow the current instructions supplied with the control and confirm that the gearbox remains in neutral throughout warm-up.

Does the V4 Have Adjustable Throttle Friction?

A specialist distributor states that the V4 has built-in friction drag to reduce slippage and throttle creep. The adjustment position and range are not published in the manufacturer descriptions reviewed.

Does the V4 Lock in Neutral?

A specialist distributor describes automatic lock-in at neutral. Multiflex also lists forward, neutral and reverse detents, but the manufacturer pages do not separately describe the lock mechanism.

Does the V4 Include Power-Trim Switches?

No power-trim switch is listed or shown in the current V4 product data. Unless expressly confirmed by the seller, engine trim must be controlled through a separate approved system.

How Does the V4 Differ From the Multiflex V3?

Multiflex V4:

• Two engines
• Two dual-action levers
• Normally four control cables

Multiflex V3:

• One engine
• One dual-action lever
• Normally two control cables

How Does the V4 Differ From the Multiflex V18?

Multiflex V4:

• Twin-engine control
• Two dual-action levers
• Each lever controls throttle and shift for one engine
• Normally four cables

Multiflex V18:

• Single-engine control
• Separate throttle and shift levers
• Red throttle handle and black shift handle
• Normally two cables

Which Ultraflex Control Is Comparable?

The Ultraflex B104 / 37924L is a close functional comparison for compatible twin-inboard installations because it is a chrome top-mount control with two dual-action levers for two engines. The Ultraflex B66 / 34732W is another comparable twin-engine inboard control.

Neither model is a verified direct replacement. Confirm cable compatibility, mounting cutout, below-panel depth, lever travel, safety-switch arrangement and engine application before substitution.

What Are the V4 Mounting Dimensions?

The product sources reviewed do not publish the overall dimensions, cutout size, mounting-hole pattern, below-panel depth, lever clearance, cable stroke or product weight.

Obtain a current V4 mounting template before drilling. Do not use the Multiflex V18 or an Ultraflex template.

What Materials Are Used?

Multiflex specifies a chrome housing. The underlying metal, lever material, chrome thickness, internal frame material, fastener grade and corrosion-test standard are not published.

• Check above-panel and below-panel clearance
• Route cables in smooth curves
• Maintain the specified minimum bend radius
• Keep cables clear of heat and moving machinery
• Align both gear mechanisms in neutral before connection
• Align both throttles at idle before connection
• Ensure no cable bottoms out before the engine linkage reaches its stop
